Provide fuel for the race the day before:
To set up a good race, you have to start eating correctly 24 hours before the race actually starts. That doesn't mean you should eat more than normal, it just means you have to pay attention to your diet.
Define the transition area.
Keep in mind that the transition area is critical to having a smooth event. Review the entrances and exits of the transition area, as well as their corresponding location and number.
Mentally review the order of things:
After setting up the transition zone, mentally rehearse your transitions. Some people make mistakes when it comes to that part. Know the order in which you will put on your bike and start riding.
Don't stay there – warm up!
Get your heart rate up to the aerobic zone 8 to 20 minutes before the race. Body and mind must be prepared before the start of the event.
Swim smart.
See the swimming course, including the buoys before its waves. Make a mental note of the buoys and relate them to something on the shore, if possible.
Foods in transition or minutes later?
When making a transition between sports modalities, the body is in a state of circulatory and respiratory adaptation. By giving food or plenty of drink at this time, the chances of stressing your gastrointestinal system are greater.
Ease in the race.
Just like on the bike, when you want to take the ramp into the race, you should move your arms at first, to help pick up your leg speed.
